Mental model
A mental model is an explanation in someone's thought process for how something works in the real world. It is a kind of internal symbol or representation of external reality, hypothesised to play a major part in cognition. The idea is believed to have been originated by Kenneth Craik in his 1943 book The Nature of Explanation. After the early death of Craik in a bicycle accident, the idea was not elaborated on until much later. Two books, both titled Mental Models, appeared in 1983 [1]. One was by Philip Johnson-Laird, a psychology professor at Princeton University. The other was a collection of articles edited by Dedre Gentner and Albert Stevens. See Mental Models (Gentner-Stevens book). Since then there has been much discussion and use of the idea in human computer interaction and usability by people such as Donald Norman and by Steve Krug in his book Don't Make Me Think. These are just a couple of examples among many, many others.
